September 5, 2013 | 3,959 views

I’m pretty sure everyone has to send files to someone else online at some point, I’ve found myself having to do it quite often. And there’s always a quandary when it comes to sending something that is somewhat confidential. How do you secure it in transit?

As for 1) and 2) they aren’t really secure at all, and as for 3) whoever is receiving the file needs to have the same software installed and your key to decrypt it – which in the majority of cases isn’t going to work.

Then you need to find somewhere to upload it (Dropbox/FTP/Yousendit etc)

Pretty much everyone you know would look at you blankly if you asked them to install GnuPG.

So now a new tool is coming out called Just Crypt It which should solve all of our problems, if you are interested in finding out more you can check out the webinar here on Sept 7th at 1PM EST / 7PM CET (Saturday).

Apart from the fact that your ‘article’ looks suspiciously like an advertisement…

Without having any details of the service that is being provided, it is difficult to make a judgement however, I’m going to. The fact that justcryptit.com is void of any relevant information suggests a closed solution – not the ideal basis for Crypto.

If there is no requirement to install software onto a device, the encryption must be carried out at the service provider. Therefore, the service provider has full access to the unencrypted data. The only possible alternative is that encryption will take place in the browser using Javascript or similar. This is not an ideal solution!

One further point: I understand that the latest version of MS Office encryption is pretty robust but I’ve not looked heavily into it. The same goes for the latest zip encryption and I know that 7-zip provides 256bit AES (and this is portable across platforms) The strength of these is directly proportionate to the strength of the key selected (to a limit)
